Seems to be a memory related issue. On compiling php in debug mode, the
crash is gone.
------------------------------------------------------------------------
[2004-11-15 06:30:12] sgovindu at yahoo dot com
Description:
------------
1. Configured mod_jk2 in apache to serve jsp, servlet as well as PHP
through tomcat.
2. Created a simple servlet which creates or destroys a HTTP session.
3. After the session gets created, accessed a PHP to print the session
data.
4. On a successive cycle of create session and destroy session more
than 5 times, tomcat crashes.
java version "1.4.2_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode)
Version: Apache Tomcat/5.0.28
Reproduce code:
---------------
<?php
$session = $request->session;
print "<P>\n";
print "The following data is in your session:<br>\n";
$e = $session->attributeNames;
while($e->hasMoreElements())
{
$name = $e->nextElement();
$value = $session->getAttribute($name);
print "$name = $value<br>\n";
}
?>
Sessions example of tomcat has been used to create or detroy a session
Expected result:
----------------
Session created in servlet should be displayed by the PHP code.
Actual result:
--------------
An unexpected exception has been detected in native code outside the
VM.
